［摘要］將消能減震技術(shù)與基礎(chǔ)隔震技術(shù)聯(lián)合應(yīng)用于澄江化石博物館結(jié)構(gòu)中，并對(duì)該高烈度區(qū)復(fù)雜鋼結(jié)構(gòu)進(jìn)行了1/30比例模型的模擬振動(dòng)臺(tái)試驗(yàn)。研究了該結(jié)構(gòu)的動(dòng)力特性和地震響應(yīng)等問題，分析了BRB，推導(dǎo)了能量方程，應(yīng)用能量原理對(duì)該結(jié)構(gòu)的地震輸入能、隔震層耗能和上部結(jié)構(gòu)耗能進(jìn)行了分析，給出了其耗能分布關(guān)系。分析結(jié)果表明，隔震層耗能占地震輸入能的90%左右，減震效果十分明顯。

Abstract:The energy dissipation technology combined with the base isolation technology were applied in the structure of Chengjiang Fossil Museum. A shaking table test on a 1/30 scaled model of an irregular steel structure in high seismic fortification intensity site was conducted. The dynamic characteristics and seismic response of the structure were studied, and the BRB was analyzed and  the energy equation was  deduced. The energy principle was used to analyze earthquake input energy of the structure, energy dissipation of isolation layer and energy dissipation of superstructure, and the energy distribution relationship was provided. The analysis results show that the energy dissipation of isolation layer accounts for about 90 percent of earthquake input energy, which proves that the base isolation system effects are very well.

Keywords:Chengjiang Fossil Museum; isolated structure; energy dissipation；shaking table test; energy analysis; high seismic fortification intensity site
